Technology (“science of craft”, from

Greek t????, techne, “art, skill, cunning

of hand”; is the collection of

techniques, skills, methods and processes

used in the production of goods or

services or in the accomplishment of

objectives, such as scientific

investigation. Technology can be the

knowledge of techniques, processes, and

the like, or it can be embedded in

machines which can be operated without

detailed knowledge of their workings.

The human species’ use of technology

began with the conversion of natural

resources into simple tools. The

prehistoric discovery of how to control

fire and the later Neolithic Revolution

increased the available sources of food

and the invention of the wheel helped

humans to travel in and control their

environment. Developments in historic

times, including the printing press, the

telephone, and the Internet, have

lessened physical barriers to

communication and allowed humans to

interact freely on a global scale. The

steady progress of military technology

has brought weapons of ever-increasing

destructive power, from clubs to nuclear

weapons.

Technology has many effects. It has

helped develop more advanced economies

(including today’s global economy) and

has allowed the rise of a leisure class.

Many technological processes produce

unwanted by-products known as pollution

and deplete natural resources to the

detriment of Earth’s environment. Various

implementations of technology influence

the values of a society and new

technology often raises new ethical

questions. Examples include the rise of

the notion of efficiency in terms of

human productivity, and the challenges of

bioethics.
